MIDAS FEA NX
MIDAS FEA NX is a specialized finite element analysis (FEA) software built to support detailed structural and civil engineering simulations by providing a user-friendly, CAD-like modeling environment paired with advanced analysis capabilities. It allows engineers to import various 3D CAD formats directly and create high-quality finite element meshes using automatic and hybrid mesh generation techniques, reducing manual preparation time and improving model accuracy. It supports both linear and nonlinear analyses, including complex simulations with high-performance solvers and parallel computing to handle large, real-world projects efficiently. FEA NX excels at refined method analysis required by design codes for structures with complex geometry, enabling in-depth evaluation of stress, deformation, and behavior under diverse loading conditions. It integrates seamlessly with the broader MIDAS COLLECTION tools and other structural analysis programs.

Calculix
With CalculiX finite element models can be built, calculated, and post-processed. The pre-and post-processor is an interactive 3D tool using the OpenGL API. The solver is able to do linear and non-linear calculations. Static, dynamic, and thermal solutions are available. Because the solver makes use of the abaqus input format it is possible to use commercial pre-processors as well. In turn the pre-processor can write mesh-related data for nastran, abaqus, ansys, code-aster, and for the free-cfd codes dolfyn, duns, ISAAC and OpenFOAM. A simple step reader is included. In addition, external CAD interfaces are available. The program is designed to run on Unix platforms like Linux and Irix computers but also on MS Windows.

Altair SimSolid
By performing structural analyses on fully featured CAD assemblies within minutes, SimSolid is the game-changing simulation technology for designers, engineers, and analysts. It eliminates geometry preparation and meshing: the two most time-consuming, expertise-extensive and error-prone tasks performed in a conventional structural simulation.
Multiple design scenarios can be simulated quickly under real-life conditions. Early CAD models, in any common format, can be used. SimSolid tolerance of imprecise geometry means that, unlike CAD-embedded simulation tools, there is no need to simplify complex geometries before analyzing designs.
SimSolid supports all typical connections (bolt/nut, bonded, welds, rivets, sliding) and analysis of linear static, modal, thermal properties, along with more complex coupled, nonlinear, transient dynamic effects.

Simcenter Nastran
Simcenter Nastran is a premier finite element method (FEM) solver for computational performance, accuracy, reliability and scalability. Simcenter Nastran includes powerful solutions for linear and nonlinear structural analysis, structural dynamics, acoustics, rotor dynamics, aeroelasticity, thermal analysis, and optimization. The advantage to having all these solutions available in a single solver is that input/output file formats are the same for all solution types, which greatly simplifies modeling processes. Available as a standalone enterprise solver or as an integrated solver in Simcenter 3D, Simcenter Nastran helps manufacturers as well as engineering suppliers in aerospace, automotive, electronics, heavy machinery, medical device, and other industries for their critical engineering computing needs so they can produce safe, reliable and optimized designs within ever shorter design cycles.
